I was at Mussel Beach near Tofino BC, for a huge rave party, and was standing on the beach looking out when I noticed what appeared to be either a signal buoy or a light on a small boat a couple of miles out, and was moving eratic pattern atlightning speed, from right to left. Then it suddenly got a lot closer moving in short bursts towards me, then disappearing only to appear in another location and continuing its movements. After a couple of minutes it disappeared.
